Shark and ray diversity in the Tropical America (Neotropics)-an examination of environmental and historical factors affecting diversity.

abstract：:Quantification of fine-scale movement, performance, and energetics of hunting by large carnivores is critical for understanding the physiological underpinnings of trophic interactions. This is particularly challenging for wide-ranging terrestrial canid and felid predators, which can each affect ecosystem structure thr...
